Abstract
The present invention is a kind of method and apparatus that disposes mist, is applied to especially on the ventilation packing machine of food fresh-keeping.
Mist collocation method of the present invention is the cylinder constancy of volume of control splendid attire pure gas, is pressed into the pure gas of required quality by its air inlet pressure of result of calculation adjustment, each pure gas is pressed into the container of splendid attire mist from cylinder again.
Device of the present invention is made up of certain number of pressure-regulating, magnetic valve, cylinder and non-metallic pipe etc.
The present invention can realize gaseous mixture in proportion easily.Be used in the fresh-keeping needs of inflation that can satisfy various kinds of foods on the ventilation packing machine.
Description
The present invention is a kind of method and apparatus that disposes mist.Be applied to especially on the ventilation packing machine of food fresh-keeping.
Experiment showed, different food mixed gas protected with certain gas or several gases.Can prolong the fresh keeping time of food, the vacuumizing-inflating packing on the existing ventilation packing machine and with the nitrogen-filled packaging of molecular sieve.Can only fill single gas, can not fill mist, more can not realize the multiple gases mixing in proportion, not satisfy the fresh-keeping needs of various foods.Existing mist configuration generally is to use gas flowmeter.The method is generally volume flow Q and the mass flow Q that records each gas
mGas flowmeter (as L, C, Q flowmeter) and secondary meter (as inclined-tube manometer) just need be set.It is higher that this method records precision, but the measurement formality is numerous and diverse, and be not suitable for moving, and is unwell on the common engineering and uses.
The objective of the invention is to provide the method and apparatus that mist disposes in proportion on a kind of common engineering.Be applied to especially take a breath and realize utilizing mixed gas protected food fresh-keeping on the packing machine.
The object of the present invention is achieved like this.
The method that mist disposes in proportion is to utilize Boyle, Robert-boyle's law, utilizes the reasonable assumption of some ideal states to develop to draw, that is:
By Boyle, Robert-boyle's law, the volume V that gas is shared, pressure P, temperature t or T.Under perfect condition be:
PV＝TR （1）
Although perfect gas reality does not exist, a lot of actual gases such as hydrogen, nitrogen, helium, oxygen etc.Under general temperature and lower pressure, can regard perfect gas as.
For the gas of certain volume and certain pressure intensity, the mass M that it has:
M＝ (PV)/(RT) μ （2）
Wherein: μ is a molecular weight.R is the gas universal constant.Generally be applicable to any gas.
Under lower pressure, Compressed Gas can think approx that T is constant, and RT is a constant A, and then following formula can be reduced to:
M＝ (PV)/(A) μ （3）
Several gas desired proportions are mixed, and promptly are that each relevant gaseous mass proportions:
M
1∶M
2∶……∶M
i＝P
1V
1μ
1∶P
2V
2μ
2……∶P
iV
iμ
i（4）
Can know by following formula and to see, change the different proportion of the quality of each gas, as long as changed the volume of corresponding gas or pressure.From engineering viewpoint, adjustments of gas is long-pending than regulating the pressure difficulty, and is also complicated on the structure.Still adopt control constancy of volume (having adopted isopyknic cylinder in the example), adjust pressure.Thereby reach the purpose that changes gaseous mass.As adopt isopyknic cylinder (do not wait as the cylinder volume, only need to add a corresponding volume ratio coefficient and get final product) then (4) formula become:
M
1∶M
2∶……∶M
i＝P
1μ
1∶P
2μ
2∶……∶P
iμ
i（5）
Can see that by following formula gas with various obtains the ratio of different gaseous masses, only need to get final product according to each gas air inlet pressure of molecular-weight adjusting of gas with various.
As dispose nitrogen and carbon dioxide gas mixture, and ratio is 1: 3, the molecular weight 28 of known nitrogen, molecular weight of carbon dioxide are 44, then their mass ratio:
Then
That is: nitrogen is 1 atmospheric pressure, and carbon dioxide is 2.1 atmospheric pressure.
The device of realizing said method comprises:
Adjust the pressure regulator valve 1 of pure gas and Compressed Gas air inlet pressure; The two-position two-way solenoid valve 2,5 of control pure gas circulation; The two-position three way magnetic valve 3 of control Compressed Gas circulation and the cylinder (example is an isometric(al)) of constant volume are formed, and all according to the need of work configuration, the switch of each valve is by computer control for quantity, and the characteristics of cylinder are that cylinder body, piston rod are motionless, and piston moves back and forth.
Advantage of the present invention is to realize the configuration of mist in proportion easily.Be used in the fresh-keeping needs of inflation that can satisfy various kinds of foods on the ventilation packing machine.Pressure regulator valve in the device of the present invention, magnetic valve can be a standard component, only cylinder need be a special purpose parts, historical facts or anecdotes is executed easily, cost is lower, and simple in structure, can move at random again, be not afraid of the characteristics of vibration, with the control of computer realization,, make this device more reliable, convenient, practical though improved into cost to each pressure regulator valve, magnetic valve.
Apparatus of the present invention have been tried out on MQ-250 pocket type ventilation packing machine and the box-packaged machine of MAX-400, can relevant protective gas desired proportions be mixed easily according to the biological nature of various food, are charged to then in packaging bag or the box.
Concrete structure of the present invention can be provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structure principle chart of the mist air distributing device of the present invention's proposition.
Describe the details and the working condition of the concrete device that proposes according to the present invention in detail below in conjunction with Fig. 1.
(5) corresponding pressure of calculating at first by formula, adjust the pressure regulator valve 1 of each pure gas porch, close magnetic valve 3, open magnetic valve 2, each pure gas enters the cavity of resorption that holds cylinder 4, with piston push up cylinder above, the pressure of closing magnetic valve 2 adjustment Compressed Gas makes its pressure than each pure gas all big, opens two-position three way magnetic valve 3, behind the two-position two-way solenoid valve 5, piston moves down, and each pure gas enters pressurizer tank by valve 5.Be connected by non-metallic pipe between each valve and the valve, form path, the switch of each valve of this device is controlled by microcomputer.
